Abstract

Different classification schemes may be used for web indexing. The authors analyze three weblogs (Biblioatipici, Letture and Andrea Marchitelli's blog) to demonstrate that different contents may be classified using the appropriate scheme. Biblioatipici is a weblog about temporary workers in libraries and Italian documentation centres indexed with a faceted scheme, home made by authors. Lecture, a diary about reading and books, is indexed by DDC. Marchitelli's blog about digital libraries and open access, is indexed by JITA, the scheme used for indexing eprints in some different open archives. The three applications are presented starting from the most complex scheme (i.e. the faceted one) to the simple but least functional (JITA), passing through a traditional bibliographic classification scheme, the Dewey Decimal Classification. The analysis demonstrates that different web contents can efficiently be classified with different schemes. In particular, with the facets one (Biblioatipici) the indexer is able to generate the needed classes in the indexing phase. Moreover with a small number of facets and foci one can obtain an exponential number of classes. Finally, one of the advantages for the user is that the faceted scheme allows multiple accesses on the basis of different information requirements, in addition to being coherent and intuitive. DDC scheme can be more suitable than the first web pages or blogs performing a sort of digital library. In this case in fact the DDC scheme constitutes a consolidated classification standard, widespread in a huge quantity of libraries and the use of a different scheme might get confusion. JITA scheme, finally, can find a huge applicability in web pages (or blogs) in LIS field showing several advantages: it's very simple and essentially pragmatic, intuitive and coherent. It's a conservative scheme because it is structurally closed, in fact it does not allow the classifier to insert new LCS's categories. If, from a certain point of view, this is a disadvantage, vice versa this feature is really useful because you get a complete matching between classes of all the web pages implemented with it.

Abstract

Content Management Systems (CMSs) are used in almost every industry by millions of end-user organizations. In contrast to the 90s, they are no longer used as isolated applications in one organization but they support critical core operations in business ecosystems. Content management today is more interactive and more integrative: interactive because end-users are increasingly content creators themselves and integrative because content elements can be embedded into various other applications. The authors of this book investigate how Semantic Technologies can increase interactivity and integration capabilities of CMSs and discuss their business value to millions of end-user organizations. This book has therefore the objective, to reflect existing applications as well as to discuss and present new applications for CMSs that use Semantic Technologies. An evaluation of 27 CMSs concludes this book and provides a basis for IT executives that plan to adopt or replace a CMS in the near future.
